CORD-ADJUSTER.

To all whom it may concern:

Be it known that I', GEORGE A. ROBINSON, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,haveinvented certain new and useful Improvements in Cord-Adjusters, ofwhich the'iollowing is a specification.

My invention relates to improvements in means for adjusting cords suchas lamp supporting cords, its object being particularly to provide adevice which may be arranged in connection with the cord or removedwithout interfering with the suspended lamp socket.

To this end my invention consists in the features of construction andcombination hereinafter particularly described and claimed. d

In the accompanying drawings forming part of this specification, Figure1 is a front view of my device shown in connection with an electriclight cord; Fig. 2 is an end view of the same without the cord; Fig. 3is a section on line x0; of Fig. 1, and Fig. 4 is a similar View 'withthe parts separated.

As shown in the drawings my de viceconsists of a ball of wood or othersuitable material formed in two sections 2 and 3, one section beinglarger than the others The section 2 is formed in its inner face withparallel grooves or openings fl through which the cord 5 i.

passed. The sections of the ball are held together by means of the screwor post 6 inset in an opening 7 in the ball section 2 and extendingslidably through the inner wall of said section with its end secured inthe section 3. A suitable spring 8 is interposed between the head 'ofthe screw and the adjacent inner wall of the ball section 2. Carried byone of the sections'is a post 9 arranged to I fit into an opening 10 inthe opposite section. The sec- In operation the cord will be placed inthe grooves 4 Specification of Letters Patent.

and doubled, 'as shown in Fig. l. The tightness with which the cord fitsinto the grooves and the angles at which it leaves the ball combines tohold. the. cord from slipping when arranged as shown'in Fig. 1, which isthe 40 normal supporting position of the cord. By enlarging ordiminishing the size of the cord-loop extending beyond the ball thelength of the cord is adjusted. When it is desired to place the cordinto the grooves or remove it therefrom, the two sections of the ballwill be drawn apart against the pressure of the spring 8 until the postis carried entirely out of the opening 10 when the sec- I tions will berelatively turned to bring the post into contact with the solid part ofthe opposite section, as I I shown in Fig. 4. The cord may then beremoved or inserted as the case may be, and the sections of the ballthen returned to the normal position shown in Fig. 3. The cord may thusbe inserted into or. removed from the grooves in the ball withoutinterfering'with a lam socket upon the end of the cord.

I claim: I 1. An adjusting device of the class described, consisting oftwo sections, one of said sections being formed with grooves in itsinner-face to hold a doubled cord, a post carried by one of saidsections and slidably supporting the other section, and a springinterposed between the post and slidable section. 1 l\ 2. An adjustingdevice of the class described comprising tivo sections, one sectionbeing formed with parallel cord 1 holding grooves in its face, a screwsecured in one section and slidahle in the other, a spring interposedbetween the headof said screw'and the adjacent section, and a postcarried by one section and arranged to fit into an opening in the other,for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.v
